Application filed October 27, 1916. Berta! No. 128,073.

To all whom it may concern:

Be it known that I, ABRAHAM S. Krasnnnn, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Im prorem'cntsin Bumpers for Automobiles, of which the following is a specification.

This invention relates 'to improvements in being formed on the arc of a circle, are passed through clamps of the particular construction shown in Figs. 2 and 3. lThese clamps comprise two members 14 and 15 II the bottom of the member 15 and the top of both members 14 and 15 are bolt openings through which are passed the ends 17 and '18 of a U-shaped bolt 19. This U shaped bolt is vented an exceedingly simple form of bumper spring which is not only so simple that 1t cannot get out of order but is so constructed that it may readily be adjusted to hold the bumper bar in exactly the desired position.

What I claim as my invention is:

1. In a bumper for automobiles and in combination with the frame thereof, bumper springs each having one end formed on an are 0 a circle, clamps for securing the arc sha ed ends of said springs to said frame, an a bumper bar secured to and su ported by the free ends of said springs, t he arcshaped ends of said springs ermitting the springs to be sprin effect.

2. n a bumper for automobiles and in combination with the frame thereof, bumper sprin s each havin one end formed on an are 0 a circle, the ee ends of said s rings being substantially vertical, clamps or securing the arc-shapedends of said springs to said frame, and a bumper bar secured to and supported by the,free vertical ends of said springs, the arc-shaped ends of said springs permitting the springs to be adjusted to obtain the best spring effect.

3. In a bumper for automobiles and in combination with the frame thereof, bumper springs, each formed of a sin 1e piece of spring material having one en adapted to occupy a substantially vertical position, and the other end bent around over thebody of adjusted to o tain the best the spring into an ai'cashaped part, clamps for securing said arc-shaped ends to said frame, and a bumper bar secured to and supported bthe free vertical ends of said springs, t e arc-shaped ends of said springs permitting the springs to be adjusted to 0 tain the best spring efl'ect.

l. In a bumper for automobiles and in combination with the frame thereof, a bumper spring, a clamp for securing said spring to said frame comprising two members between which the end of the spring is clamped, a bolt for holding said members in place, and a U-shaped bolt securing said clamp to said frame, one of the ends of said U-shaped bolt cooperating with the aforesaid bolt to clamp the spring between said clamping members.

5. n a bumper for automobiles and in combination with the frame thereof, a bumper spring, a clamp for'securing said .sprin and a Ushaped bolt for securing said 0 amp to said frame, said bolt having a recessed part having two gripping edges contactin with said rame.

In testimony whereof I aflix my signature in presence of two witnesses.
